We are familiar with Sending Email Using Asp.Net With C#. But today, we are going to teach you how to send email using ASP.NET Core 1.1 with MailKit. We can implement it in ASP.Net Core very easily as compared to the previous versions of ASP.NET.

Before reading this article, you must read the articles given below for ASP.NET Core knowledge.

MailKit is a cross-platform mail client library built on top of MimeKit. That means we get all the mail sending libraries from MailKit, such as – Simple Mail Transfer Protocol (SMTP) etc.

Simple Mail Transfer Protocol (SMTP)

Simple Mail Transfer Protocol (SMTP) is a TCP/IP protocol used in sending and receiving e-mail. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another.The messages can then be retrieved with an e-mail client using either POP or IMAP.

The following is a list of SMTP Server and Port Numbers.

Assemblies Required

The following assemblies are required for sending email using ASP.NET Core with MailKit.

New .NET Core tooling is available in Visual Studio 2017 by default. In the Dependencies folder, every package tool has separate folder like MailKit saved into NuGet folder. If you have a client side tool like bower, then its dependencies are saved into it’s folder.

When you are sending mail with your “gmail” account, enable less secure apps so that you will be able to login from all apps. Otherwise, it will throw authentication error like 5.5.1 authentication.

Remove 2-Step Verification.

In the following code, we can mention username for “gmail” account but in other service like “hotmail”, we must provide the full email address because other Microsoft accounts, like Outlook, live, etc. have the same SMTP Server Address “smtp.live.com”.

client.Authenticate("From Address Email", "Password");

csproj

In previous version, ASP.NET Core 1.0 contained all the versions & dependencies in project.json file but in new version, i.e., ASP.NET Core 1.1, they are saved in csproj.

Feeling great & Looking Smart. I know every one is excited for the new release of “Visual Studio 2017”. Yes , Microsoft Visual Studio celebrated it’s 20th years of glory with all tech lovers in the world love it. Now, it has come up with lots of excitement. Thus, I am happy to share the important features of Visual Studio 2017 with all the tech lovers.

Visual Studio 2017 System Requirements

The following are the minimum requirements of Visual Studio 2017 installation.

We can choose the appropriate development section from Visual Studio Workloads. I selected “ASP.NET and Web development & .NET Core cross-platform development”. It also contains around 5.50 GB. Thus, If you select all Workloads, then it will reach 50 GB+.

Individual components

We can choose the required component from this section.

Language packs

We can use different languages in Visual Studio. Thus, we can choose the appropriate language in this section.

Installation Process

We are going to install Visual Studio Community 2017 edition in our machine. Ones the following process is complete, we can launch & access the new features in Visual Studio 2017.

Features in Visual Studio 2017

The following are the new features in Visual Studio 2017.

Live Unit Testing

This feature is only available in Visual Studio 2017 Enterprise edition. Without running the solution, we can easily test the Application because few hidden background process happens in our Application through “Live Unit Testing”. We can enable Live Unit Testing for which you need to go to the “Test” command of the top-level menu bar in VS, choose “Live Unit Testing”, then “Start”.

We noticed that 3 symbols appeared in our code due to running on background Live Testing.

Cross Sign – line of executable code. The test is covered and it indicates that a failure test.

Tick Mark – line of executable code. The test is covered and it indicates that a success test.

Minus – line of executable code. Not yet covered a single Test.

Dotted Line

The is a very cool feature in Visual Studio 2017 because this option helps to identify the exact open and close curly braces “{}” through dotted line in our code. This dotted line is really helpful for when you are working on a bulk amount of code in a single page.

Filttered IntelliSense Search

The new Filtering IntelliSense Search option is available in Visual Studio 2017. This option is one of the powerful way to consume the search time in our code. The following IntelliSense bottom tray contains icons as Properties, Interface, Modules, Namespaces, Enums, Classes, Constants etc. For example, if i want to search an Interface, then I can choose an Interface Icon from the bottom of the tray, else it will show all the possible contents in our solution.

Improvements Of Navigation Controls

Go to All ( Cntrl + T )

Go to Line ( Cntrl + G )

Go to File ( Cntrl + 1 + F )

Go to Type ( Cntrl + 1 + T )

Go to Member ( Cntrl + 1 + M )

Go to Symbol ( Cntrl + 1 + S )

Go to All ( Cntrl + T )

Press “Cntrl + T”, then it will display one tray above the search bar. Thus, we can search the content with the help of the options given below like Line/Files/Types/Members/Symbols. For example, I want to search type in our entire solution or an Application. Now, choose “Type” Icon in the tray and type in the search bar, so it will filter and show the exact results as much as faster than the earlier versions of VS. The shortcut is “Cntrl + 1 + T”.

Find All Reference ( Shift + F12 )

We can find all the references in our entire solution. The highlighted one is all the reference results by a combination of project, definition and path.

Code Suggestions

This is a very exciting feature in VS2017. It gives us the good code practice in our Application. The code given below notices that we have written an “If” condition without curl braces. Thus, it gives us the suggestion tp add the curl braces to understand the code.
